While on the set of “Sharknado,” SyFy Channel’s newest original flick, Tara Reid could barely keep from laughing.

“Trust me, we had no idea,” she said of the film’s instant popularity, in a recent telephone interview. “We were like, 'what are we making?' Because there were no real sharks there. We were running away from nothing. We were laughing so hard and just having fun.”

“It’s always great coming back home,” said the Wyckoff native. “I love going back to Jersey to see my people.”

Her birthday bash — also The Pool’s Official Halloween Bash — will feature music by DJ Hollywood and The Beatclan’s finest and a costume contest.

Probably best known for playing Vickie in the “American Pie” series, Tara recently returned to the spotlight for her role as April Wexler in “Sharknado.”

“It’s like a global sensation,” Tara said in amazement. “There were 5,000 Tweets a minute. We broke all kinds of records and didn’t do any promotions or press junkets for it. It was like winning the lottery.”

“Sharknado” is the story of a freak hurricane in Los Angeles which pulls countless sharks out of the Pacific and drops them on the city and surrounding area.

Tara said, while on set with co-stars Ian Ziering and John Heard, she had to control her laughter.

“I was like, ‘I can’t believe what I’m doing,” she laughed. “Now, they’re talking about making a part two. I would have bet nothing on this.”

On a trip from Mexico home to L.A. shortly after the film's release, Tara got her first taste of the film’s popularity.
